Advice

So I was on my fiancé’s computer putting photos on it and saw some of his old photos they were adorable then the further I got the worse it got.. it was all of his ex. Naked pictures of her every where. All these quotes about how much he loves her and a promise ring ( that looks exactly like my engagement ring but different colors) talking about babies and marriage.. like he loved her more than he’s ever even remotely shown me.. how do I cope with this
